A Few Things You Probably Didn't Know About the Iowa State
Bird:
- Most finches molt once per year in the fall.
The American Goldfinch molts a second time, in the springtime.
The second molting brings out their beautiful yellow breeding color,
supporting their nickname "wild canary".
- The female will often leave the male, with
the young birds still in the nest, to find another mate.
- In the winter, these birds can be found in large
flocks. During the breeding season, they will feed in much
smaller groups.
